実験手順
A solution of 7-[2-(2-aminothiazol-4-yl)-2-((Z)-methoxyimino)acetamido]-3-[(2,5-dihydro-6-diphenylmethoxy-2-methyl-5-oxo-1,2,4-triazin-3-yl)aminomethyl]ceph-3-em-4-carboxylic acid (400 mg.) in anisole/TFA (1:1 v/v; 10 ml.) was allowed to stand at ambient temperature for 20 minutes. The solvent was evaporated and the residue was dissolved in an aqueous ammonium carbonate buffer, pH6, and purified by HPLC using ammonium carbonate buffer/MeOH 92:8 v/v as eluant to give 7-[2-(2-aminothiazol-4-yl)-2-((Z)-methoxyimino)acetamido]-3-[(2,5-dihydro-6-hydroxymethyl-5-oxo-1,2,4-triazin-3-yl)aminomethyl]ceph-3-em-4-carboxylic acid (yield 25%) having the following nmr in solvent B:--3.52(s,3 H); 3.6(s, 2 H); 4.04(s, 3 H); 4.4(s, 2 H); 5.18(d,1 H); 5.84(d, 1 H); 7.1(s, 1 H).
